Turkey - weather in September

September is the first month of autumn in Turkey, and it is still a hot and sunny month on the western and southern coast, and also on the plateau, where, however, it gets cool at night.

On the plateau, the average temperature is 19 °C (66 °F) in Ankara, at 900 metres (2,950 feet), 18 °C (64.5 °F) in Cappadocia (see Kayseri), just above 1,000 metres (3,300 ft), while it is lower in the areas located at higher altitudes (see Erzurum, Van). On the Black Sea coast, the average is 22 °C (71.5 °F) in the western part (see Istanbul) and 21.5 °C (70.5 °F) in the eastern part (see Trabzon). On the coast of the Aegean Sea (see Izmir), the average is around 23 °C (73.5 °F), while on the southern coast (see Antalya, Mersin) it is 26/27 °C (79/81 °F).
Sometimes, there can still be heat waves, especially at the beginning of the month, during which the temperature can reach 35 °C (95 °F) even on the plateau at around 1,000 meters or 3,300 feet (see Ankara, Cappadocia), while it can even reach 38/40 °C (100/104 °F) in the inland valleys of the west, such as that of the Meander or Büyük Menderes river (see Denizli, Pamukkale), on the coasts and plains of the south (see Antalya, Adana), and also in the south-east, on the plateau of Kurdistan (see Diyarbakir). Instead, the north coast, especially in the eastern part (see Trabzon, Rize), where the sun doesn't shine very often, is more sheltered from heat waves.

As for the rainfall, it is still rare almost everywhere, even though it increases a little compared to the summer months. The rainiest area is the northernmost one, in particular, the eastern part of the Black Sea coast (see Trabzon), and even more so the easternmost one, on the border with Georgia (see Rize), where 250 mm (10 in) fall in month and the climate is almost oceanic.

In September, the sea in Turkey is warm enough for swimming on the Aegean coast (see Izmir) and on the Black Sea coast (see Istanbul), especially in the eastern part (see Trabzon), while it is pleasantly warm on the southern one (see Antalya, Mersin).
